Answer:
The chloroplast
Explanation:
The choloroplast takes in nutriets (sunlight) and converts it into energy for the plant
Answer:
B is INCORRECT
Explanation:
Action potential in contractile cells can be divided into 3 phases
1. Rapid depolarization; caused by fast influx of sodium ions into the cells. Last a few milliseconds.
2. Plateau phase: This is a sustained positive membrane potential, after rapid depolarization, caused by a balance between calcium ion influx and slow potassium ion efflux.
3. Rapid repolarization: Eventually there's a closure of all other ion channels except the potassium ion channels causing rapid efflux of potassium ions, returning the membrane potential back to negative.
A refractory period usually occurs after undergoing an action potential. During this time no action potential can occur.
The Vikings were able to effectively use their longboats because of the
following:
- The boats moved swiftly and efficiently in the water making it easy to evade their enemies.
- The longboat rode high in the water, allowing it to sail further in the shallow water and transport the vikings closer to shore.
- The long boat was not only fast, but also light enough to be carried over land fortifying bridges.
Vikings made use of the long boat because it was light weighted and the
people could carry it.
The light weight of the ship also ensured that it moved swiftly and was able
to sail in shallow waters.
